BORDER-WIRE REINFORCEMENT FOR SPRING-SEAT STRUCTURES.

Specification of Letters Patent.

Application filed June 17, 1909.

Patented Sept. 13, 1910. Serial No. 502,758.

useful Improvements in Border-Wire Rein- I forcements for Spring-Seat Structures; and

I do declare the following to be a full, clear, and exact description of the invention, such. as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theiigures of reference marked thereon, which form a part of this specification.

This invention relates to border wire reinforcement for spring seat structures, as will be hereinafter more fully set forth andj claimed.

The object of the invention is to provide for strengthening the top border wire of a spring seat structure in a manner to obviate undue weight and at the same time afford a resiliency which will cause the border wire to spring back or return to its normal position after relieved of the pressure which is applied to the front edge of the seat in the operation of shoving it into place in the scat frame.

The above object is attained by the structure illustrated in the accompanying drawings, in which Figure 1 is a plan view of a spring seat structure showing. my. reinforced border wire applied thereto. Fig. 2 is a transverse section as on line 2-2 of Fig. 1. Fig. 3 is a plan view showing the arrangement for increasing the reinforcement shown in Fig. 1. Fig. 4 is a fragmentary view in perspective, showing a clip embracing the border wire and tying the reinforcing wires thereto. Fig. 5 is a perspective view of the blank from whichsaid clip is ilormed. Fig. (i is an enlarged transvm'se secl ion through one of the base slrips of the scat structure.

In spring scat structures as ordinarily madc'whcrc a light or weak top border wire is employed, the prcssurc necessary against the front edge of the spring cushion to force said. cushion into place in the scat frame, bonds the border wire inwardly and dcstroys the straight linc of thc front margin of the scat, thereby giving the cushion an unsightly appearance. I o\'crc.ou|c said ohjcctionahlc feature of the ordinary spring scat construction by reinforcing the border wire 1 through the addition of a second border wire 2. which lies within the first border wire and is secured thereto by clips 3, comprising a plate, as shown in Fig. 5, having at one edge the rejecting tongues 4, and at the opposite ec ge the central tongue 5 adapted to lie between the ton ues 4 when said tongues are folded around the border wires in opposite directions, as shown in Fig. 4. The primary border wire 1 is attached to the border springs 6 by means of suitable clips 7, so that by means of the clips 3, the secondary or reinforcing border wire 2 becomes also attached to the springs through the mediumof the wire 1.

By reinforcing the border wire, as shown,

it is materially strengthened so as to resist lateral pressure without bending, yet the resiliency of the border wire is not destroyed, nor the flexibility of the spring cushion impaired. When reinforced, as shown, the border wire will spring inwardly when pressure is applied thereto, but will return to a straight line when the pressure is removed, leaving the front margin of the cushion straight. By extending the reinforcing wire entirely around the frame, the front is zulditionally strengthencd because the sides are held from springing outwardly by an inward application of pressure at the front.

The bottom of the springs are seated upon transverse base strips 8, the ends of which are connected by a lmttonrbordcr wire 9.

in unusually heavy structure, or in cases where more strength is required in the top border wirc than is afforded by the two wircs shown in Fig. 1, said wires may be additionally strcngthcmal by a third border wire 10, shown in Fig. 3, which extends across the front within the wire 2 and partially along the sides. said third wire being bound to the wires 1 and 2 by the clips 3. By binding lhc plural border wires together as shown. they are braced one against the olhcr and their strcnglh greatly increased without adding malcrially to the weight of the structure.

Having thus fully set forth my invent-ion, what i claim as new and desire to secure by Letters Patent, is:--

1. In a spring scat structure, a base, bordcr springs mounted upon the base, a resilicut border wirc embracing the tops of said springs, clips counccting the upper cuds of said springs to said border wire, a

resilient reinforcement for the border wire conforming to and lying within the plane thereof and clips connecting said reinforcement directly to said border Wire.

' 2. A spring seat structure. comprising border springs, a resilient border wire eIn-' bracing said springs at the-top, a second resilient border wire conforming to and re- .inforcing said first-mentioned border wire,
